<!----------- Notes ---------->
<TR align="left" valign=top>
<TH>NOTES</TH>
<TD>
<UL>
    <LI>Since the message body may be very large, calling smfi_replacebody may significantly affect filter performance.
    <LI>If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
    <LI>For smfi_replacebody, filter order is important.  <B>Later filters will see the new body contents created by earlier ones.</B>
    <LI>A filter which calls smfi_replacebody must have set the
    <A HREF="smfi_register.html#SMFIF_CHGBODY">SMFIF_CHGBODY</A> flag.
</UL>
